Empire Four Kingdoms

As a server developer, I specialized in building robust and scalable applications using Java, MySQL, and AWS Lambda. Working closely with cross-functional teams, I managed our projects through JIRA while focusing on optimizing system performance and strengthening data security. I developed and implemented new game features for our live service game, continuously expanding the player experience through regular updates. I contributed to maintaining and enhancing the company's server infrastructure, helping ensure systems operated efficiently and reliably.  

Empire Four Kingdoms is a medieval strategy mobile game where players build and manage their own castle empire. Players gather resources (food, wood, stone, and gold) to construct buildings, train troops, and expand their territory through conquest.

The game focuses on three main aspects: combat (attacking and defending castles), diplomacy (forming alliances and trade agreements), and resource management. Players can participate in events and quests for rewards, join alliances for support, and engage in strategic warfare with other players.

The ultimate goal is to become the most powerful ruler by continuously expanding, defending, and strengthening your empire through military might and diplomatic relations.
